228 LICHENS. 



all the brandies are beset with numerous branelilets, 

 crowding one upon another on either side the stern, vary- 

 ing in length from a few lines to half an inch. The 

 lateral branches bear very large greenish ochre apotheeise, 

 fringed like the branches with tiny branelilets ; the 

 branches grow in thick tufts, and they and their branch- 

 lets are covered with grey powder. This lichen is 

 frequently found. We have specimens from these Tre- 

 lawny woods, Cornwall, from York, Kent, and Wilts ; but 

 never did I see it in such abundance as in the Chace 

 wood, near Eoss, in Herefordshire. There the woodland 

 paths were strewed with its fully branched tufts after 

 each oft recurring gale. Old Gerarde writes of this "flour- 

 ing branched moss," and thus describes it, "There is 

 bftentime found upon old Okes, Beeches, and suchlike 

 overgrown trees, a kinde of Mosse having many slender 

 branches, which divide themselves into other lesser 

 branches, whereon are placed confusedly many very small 

 threads, like haires, of a greenish ash colour. Upon the 

 ends of the tender branches there cometh forth a floure, 

 in shape like unto a little buckle, or hollow mushroom, 

 of a whitish colour, tending to yellownes, and garnished 

 with the like leaves of those upon the lower branches." 



The Hairy Usnea (U. hirta, Plate X VI, Jig. 1G) grows 

 on dead branches, shrubs, and pales. It forms a sturdy 

 little shrub, its branchlets thorn-shaped, and its whole 

 aspect firm and strong. We find it frequently in the 

 same habitats as its brother. 



The Usnea Barbata, or Hairv Usnea, is found in old 

 woods in hilly countries. It is jointed, very slender and 

 long, and hangs like bunches of hair from the trees.
